Hidden deck fastener system
A deck system employing a plurality of substantially hidden fasteners to couple the floor boards of the deck to the joists. Each hidden fastener is rigidly coupled to a respective joist and positioned between a pair of adjacent floorboards. Each fastener forms a mating relationship with specially configured sides of the boards to thereby rigidly couple the boards to the joists.
The present application claims the priority benefit of U.S. patent application Ser. No. ______, entitled “Grooved Decking Board,” filed contemporaneously herewith, the entire disclosure of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to decks. In another aspect, the invention concerns an improved deck system employing hidden fasteners to couple the floor boards of the deck to the supporting joists.
2. Description of the Prior Art
Conventional deck systems typically employ an elevated floor portion surrounded by a railing and supported by upright columns. The floor portion of the deck usually includes a number of laterally spaced supporting joists and a plurality of floor boards extending across and supported by the joists.
Traditionally, the floor of a deck has been constructed by nailing, stapling, or screwing the floor boards to the joists, while maintaining a slight gap between adjacent floor boards. Conventional methods of attaching the floor boards to the joists can be time consuming, and the conventional fasteners used to connect the floor boards to the joists can be unsightly. In addition, the conventional fasteners may loosen over time, thereby causing the floor boards to creak when walked over. Worse yet, a loosened fastener can protrude upwardly from the floor boards, thereby causing an unsightly and dangerous condition.
OBJECTS AND SUMMARY OF THE INVENTIONIt is, therefore, an object of the present invention to provide an improved deck system employing a hidden fastener that is not visible from the top of the deck.
Another object of the invention is to provide an improved deck system which is less time consuming to construct than conventional deck systems yet conceals the fasteners.
A further object of the invention is to provide an improved deck system that prevents creaking of the floor boards on the joists.
Still another object of the invention is to provide an improved deck system that eliminates the possibility of having loosened fasteners extending above the floor boards of the deck.
Yet another object of the invention is to provide an improved method of constructing a deck.
It should be understood that the above-listed objects are only exemplary, and not all the objects listed above need be accomplished by the invention described and claimed herein.
Accordingly, in one embodiment of the present invention, there is provided a deck system comprising a plurality of laterally spaced joists, a plurality of boards extending across and supported by the joists, and a plurality of fasteners rigidly coupled to the joists and each presenting a pair of protrusions. Each of the boards defines a pair of longitudinally extending grooves on generally opposite sides of the board. Each of the protrusions of the fasteners is received in a respective groove of a respective board in a substantially complemental fashion.
In another embodiment of the present invention, there is provided a deck system comprising a plurality of laterally spaced joists, a plurality of boards extending across and supported by the joists, and a plurality of fasteners rigidly coupled to the joists and each presenting a pair of protrusions. Each of the boards presents a pair of similarly configured opposite sides. Each of the sides of the boards includes a pair of spaced-apart longitudinally extending lips presenting opposing inwardly facing surfaces. Each of the protrusions of the fasteners contacts both of the inwardly facing surfaces.
In a further embodiment of the present invention, there is provided a method of coupling a plurality of boards to a plurality of support members. The method comprises the steps of: (a) rigidly attaching a first fastener to one of the support members; (b) positioning a first board across the support member and against the first fastener to thereby form a mating relationship between the first board and the first fastener; (c) positioning a second fastener against the first board to thereby form a mating relationship between the first board and the second fastener; and (d) rigidly attaching the second fastener to the support member while maintaining the mating relationship between the first board and the first and second fasteners.
In yet another embodiment of the present invention, there is provided a board comprising an elongated body presenting a pair of similarly configured sides. Each of the sides presents a normally-upper lip and a normally-lower lip. Each of the sides includes a longitudinal groove defined between the normally-upper lip and the normally-lower lip. The groove includes an inner-most surface representing the deepest portion of the groove. The normally-upper lip extends further from the inner-most surface than the normally-lower lip.

28. A deck system comprising:
- a plurality of laterally spaced joists;

- a plurality of fasteners rigidly coupled to the joists, each of said fasteners presenting a pair of protrusions having a height “F,” each of said protrusions being received in a respective groove of a respective board in a substantially complemental fashion, wherein “E” is at least 1% greater than “F.”
29. The system of claim 28, wherein “E” is at least about 2% greater than “F.”
30. The system of claim 29, wherein “E” is at least about 5% greater than “F.”
31. The deck system of claim 28, wherein the protrusions exert a downward holding force on the lower lips when the protrusions are at least partially received within the grooves.
32. The deck system of claim 31, wherein the downward holding force is due to the thickness of the lower lips being at least 1% greater than the height of the protrusions.
33. The deck system of claim 31, wherein the downward holding force inhibits upward movement of the boards relative to the fasteners and joists.
34. The deck system of claim 31, wherein the fasteners are comprised of a resilient material that allows the protrusions to be elastically flexed when the protrusions are at least partially received within the grooves.
35. The deck system of claim 34, wherein the flexing of the protrusions facilitates maintaining the downward holding force on the lower lips.
